Tektronix 576/176 Curve Tracer System Semiconductor Testers

Description

The Tektronix 576 Curve-Tracer System continues to hold the title ''standard of the industry." This general-purpose curve-tracer system performs well in applications where high-current testing is required.

With the Standard Test Fixture, the collector supply of the 576 delivers up to 220 W peaks to the device under test. The step generator can deliver up to 2 A in both its current and voltage modes of operation. With the 176 High-Current Test Fixture, the 576 is capable of pulsed­ collector operation up to 200-A peak.

Alphanumeric indicators provide readout of vertical and horizontal deflection factors, step amplitude, and Beta/div or gm/div. The Beta or gm readout saves the operator from the arithmetic usually necessary to arrive at these parameters. These indicators also provide a permanent record of major knob settings in 576 CRT photographs.

Features

  • Calibrated display offset
  • Adjustable current limiting in the step generator; either 300 or 80 micro second pulse width in pulsed base operation
  • Push buttons to check display zero and calibration
  • Illuminated graticule
  • Safety interlock protects the operator from dangerous voltages

Specifications

Accuracy-Incremental 

Within 5%, between steps, within 10% with X 1.O Mult. Absolute: Within 2% of total output including offset, or 1% of amplitude setting, whichever is greater? Offset Multiplier: Continuously variable from 0 to X10 the amplitude setting, either aiding or opposing the step polarity

Step Rates

Selectable at X1, X2, or X4 line frequency

Pulsed Steps

80 or 300 micro second width

Step/Offset  Polarity

Same as Collector­ Supply polarity and positive in ac position. Polarity can be independently inverted with Step/Offset Polarity control or from the test fixture

Step Family

Repetitive or single family
